The objective of this work is to create the information system for monitoring of annual catch spatial distributions. The system is based on ArcView 3.2 by ESRI and RDBMS Oracle8i by Oracle. Russian fishing ships daily data from 1995 to 2001 are used to calculate spatial distributions of annual catch for any object of fishing. The Oracle8i database performs all calculations. By joining of two tables – one from ArcView and another from Oracle database – the polygonal themes are created. Their attribute tables contain records with the sum catches for each polygon and object of fishing. Resulting themes visualize the process of spatial evolution of annual catch from year to year. Some examples for the Okhotsk Sea are presented.
